Flagship course
Coverage Insight Studio
A six-week live program for QA leads, staff engineers, and product partners who need application analytics for testing coverage insights they can defend in a release meeting.
Modules
Export archaeology
Inventory tools, formats, and silent filters that reshape your coverage numbers before they reach a dashboard.
Gap narratives
Write short explanations for unexplained drops — instrumentation drift, deleted paths, or intentional exclusions.
Suite cohorts
Compare families of tests over time without collapsing them into one misleading average.
Risk tags
Build a shared taxonomy so coverage conversations reference blast radius, not vibes.
Stakeholder briefs
Produce a one-page visual brief with caveats your CPO can skim in three minutes.
Hygiene cadence
Schedule metric reviews and retire tiles that no longer earn trust.
Learning outcomes
- Distinguish measurement gaps from product decisions
- Brief leadership without overselling a percentage
- Maintain a readable coverage dashboard for a full quarter
- Facilitate a peer critique using the alumni worksheet pack

FAQ
Do I need a specific coverage tool?
No. We work from CSV and JSON exports common to Istanbul, JaCoCo, SimpleCov, and similar reporters. Bring whatever your CI already produces.
Is this a coding bootcamp?
No. You will write light scripts for cleanup, but the emphasis is analytical judgment and communication.
What is a real limitation of this course?
We do not remediate flaky tests or rewrite your suite. Teams hoping the studio will raise a coverage percentage by itself leave disappointed — the program teaches interpretation and process, not bulk test generation.
Can my whole team join?
Yes — look at Insight Circle on the pricing page, or email us for mixed seat options.
Course reviews
“Module 3 on suite cohorts was the piece our mobile chapter needed. The homework took longer than estimated when our export had nested packages.”
I came for charts and left with a ritual: every other Tuesday we delete one unused tile. Oddly motivating.
